ASTM A554 TP304 Stainless Steel Welded Building Pipe
ASTM A554 TP304 Stainless Steel Welded Building Pipe
ASTM A554 TP304 is a specification for welded stainless steel mechanical tubing, commonly used in applications requiring high corrosion resistance, appearance, and mechanical properties. "TP304" refers to 304 grade stainless steel, with a chromium content of approximately 18% and a nickel content of approximately 8%. Key characteristics of this specification include its welded manufacturing process (without filler material), suitability for structural, decorative, and mechanical applications, and minimum mechanical properties (tensile strength ≥ 85,000 PSI, yield strength ≥ 35,000 PSI).
What are the specifications of 304 stainless steel pipe?
The specifications of 304 stainless steel pipe include its chemical composition (18-20% chromium, 8-11% nickel), minimum yield strength of 205 MPa, and minimum tensile strength of 515 MPa. This pipe is available in both seamless and welded forms, with a wide variety of sizes and standard wall thickness grades (such as SCH5, SCH10, SCH40, and SCH80). Key dimensional specifications include nominal diameter, outer diameter (OD), wall thickness, and inner diameter (ID).
ASTM A554 TP304 Stainless Steel Welded Pipe for Construction Applications
ASTM A554 is a standard specification for welded stainless steel mechanical tubing. It covers tubing used in mechanical applications where high corrosion resistance and aesthetics are required.
TP304 refers to 304 grade stainless steel, widely used due to its excellent corrosion resistance, high strength, and good formability. It belongs to the austenitic stainless steel family and contains 18% chromium and 8% nickel, giving it extremely strong oxidation and corrosion resistance.

Gnee Steel specializes in the production of a wide range of stainless steel products. Gnee Steel's product packaging includes: Steel Strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during ocean shipping, and then secured with steel strapping. Wooden Cases/Crates: Pipes are typically packaged in wooden cases or crates to protect the pipes during transportation, especially those that are longer or have larger diameters. Seaworthy Export Packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin Packaging: This prevents rain, seawater, and other external factors from penetrating the export crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in the aerospace, chemical, power, automotive, and nuclear energy sectors, and we can provide customized alloy material solutions based on customer needs.
